Abstract

See full text

A quiet water closet rim and a method for venting air from a rim cavity of a water closet. The rim has a horizontally oriented annular cavity and is selectively supplied with pressurized water by a flush mechanism. A series of perforations in the rim permits the pressurized water within the rim cavity to exit the rim in the form of a spray. The rim is also provided with a vent passageway having an inlet open into an upper portion of the cavity and an outlet open into the atmosphere. As pressurized water fills the cavity, a portion of the air within the upper portion of the cavity is vented through the vent passageway.
